Figure 5, p. 186, shows three trees treated with one application of 

 Bordeaux mixture and Paris green May 6th, before flower buds had 

 expanded. Photograph taken September 19th. 



Figure 6, p. 187, shows two trees treated with copper sulphate April 

 1 st, two applications of Bordeaux mixture and Paris green May 3d and 

 10th, before and after blooming. Photograph taken September 19th. 



Figure 7, p. 187, one tree in foreground treated with one application 

 of copper sulphate April 1st. Photograph taken September 19th. 



Figure 8, page 189, tree treated with one application of Bordeaux 

 mixture May 10th, after the blossoms had fallen. Photograph taken 

 September 19th. 



Figure 9, page 189, shows Grimes golden trees treated with one 

 application of copper sulphate and two of Bordeaux mixture. Photo- 

 graph taken October 1st. 



Figure 10, page 190, photograph of men spraying Ben Davis trees 

 for apple scab fungus during the latter part of June. Shows the difficul- 

 ties which are often met with. It is an illustration too which serves to 

 force upon our minds the fact that the spraying and pruning of apple 

 trees are two very closely related subjects. If the trees are not reason- 

 ably open so as to admit a free circulation of light and air the tree top 

 will furnish an excellent breeding place for fungous diseases, and when 

 once started the latter are impossible to get at with spraying solutions. 

 It is almost impossible to spray such trees to advantage, and the amount 

 of material necessary in such cases, together with time and expense, 

 makes the matter of pruning a necessity. 



Figure n, page 190, shows specimens of the best apples from trees 

 treated as follows: No. 1, sprayed with copper sulphate and three appli- 

 cations of Bordeaux mixture; No. 2, two applications of Bordeaux 

 mixture — before and after blossoms appeared; No. 3, unsprayed. 



Spraying Machinery. 



We are constantly asked to give information regarding the best 

 spray pumps and other appliances necessary for spraying; and for this 

 reason the Station has been making a thorough test of machines sold by 

 a few of the leading manufacturers. In looking over the machinery so 

 far experimented with we have learned that the purchaser should bear in 

 mind that the money invested in a pump is practically lost should the 

 machine last no longer than one season. He wants a machine that is 

 durable; one that will give the greatest force with the least power; and one 

 that will be within reach of his purse. The cheap iron pumps are rarely 

 long-lived, and are usually wholly unfit for spraying purposes. They 

 will not stand the work, are too easily broken, or are destroyed by the 

 action of copper sulphate. The desirable points in a pump may be 

 summed up as follows:
